arXiv:2602.04396v2 Announce Type: replace Abstract: Distributed training of foundation models via $\texttt{DDP}$ is limited by interconnect bandwidth. While infrequent communication strategies reduce synchronization frequency, they remain bottlenecked by the memory and communication requirements of optimizer states. Low-rank optimizers can alleviate these constraints; however, in the local-update regime, workers lack access to the full-batch gradients required to compute low-rank projections, which degrades performance. We propose $\texttt{LoRDO}$, a principled framework unifying low-rank opti
The increasing scale of foundation models is pushing the limits of current distributed training methods, making communication bandwidth and optimizer states significant bottlenecks.
This research provides a potential solution to a critical scaling challenge in AI model training, directly impacting the feasibility and cost of developing even larger and more capable AI systems.
The computational and memory requirements for distributed AI training could be significantly reduced, enabling more efficient and potentially larger model development, especially when interconnect bandwidth is limited.
